Chronic pain and subfertility are the main symptoms of concern in women with endometriosis. In order to find new therapeutic options to suppress the pain, translational animal models are indispensable. We have developed a new automated, exp…

Human reproduction update ·doi:10.1093/humupd/dmy020

BACKGROUND: The drug research and development (R&D) for endometriosis/adenomyosis has been painfully slow. Most completed clinical trials on endometriosis did not publish their results, and presumably failed. While few published trials did …

OBJECTIVE: To determine [1] expression levels of both DNA methyltransferases (DNMTs) and methyl-CpG-binding domain proteins (MBDs) in human endometrium throughout the menstrual cycle and in eutopic and ectopic endometrium of patients with e…

It is widely known that angiogenesis plays a key role in endometriotic lesion formation and development. Antiangiogenic treatments aimed at inhibiting new vessel formation have proven efficient in experimental models. However, as antiangiog…

Human Reproduction ·doi:10.1093/humrep/den153

BACKGROUND: In this study, we characterized the fibromuscular (FM) tissue, typical of deeply infiltrating endometriosis, investigated which cells are responsible for the FM reaction and evaluated whether transforming growth factor-beta (TGF…

BackgroundFundamental and genetic differences between women in the endometrium may cause some to develop endometriosis, whereas others do not. Oral contraceptives (OC) may have an effect on the endometrium, rendering the development of endo…

Reproductive sciences (Thousand Oaks, Calif.) ·doi:10.1177/1933719107303436

Deep infiltrating endometriosis is characterized by the presence of nodular lesions largely composed of fibromuscular tissue. Transforming growth factor beta 1 (TGF-beta1) is the cytokine most causatively associated with disorders character…

BACKGROUND: Alterations in the progesterone receptor (PR) are considered a risk factor for the development of endometriosis. In this study, the frequencies of the PROGINS and +331G/A polymorphisms of the PR gene were determined in deep infi…

A prospective study was performed to determine the effects of the angiostatic compounds anti-hVEGF antibody, TNP-470, endostatin, and anginex on the vascularization and on endometriosis-like lesion formation in the chicken chorioallantoic m…

Endometriosis, defined as the presence of endometrial tissue outside the uterus, is an estrogen-dependent disease which causes pelvic pain and subfertility in women of reproductive age. The condition has a dramatic impact on the professiona…

It is known that angiogenesis is of pivotal importance for the development of endometriosis. However, in the treatment of endometriosis patients, prevention of endometriosis lesion development only will not be sufficient as a therapy. Treat…

Human Reproduction ·doi:10.1093/humrep/deh408

BACKGROUND: Matrix metalloproteinases (MMPs) are essential for extracellular matrix remodelling and may contribute to the development of endometriosis. Transplantation of endometrium onto the chicken chorioallantoic membrane (CAM) results i…

Many women harbour spots of peritoneal endometriosis without having any symptoms; this is referred to as the phenomenon endometriosis. Some of these women go on to develop symptomatic endometriosis. Although we know the factors potentially …

Peritoneal endometriosis is the result of ectopic implantation and growth of endometrium tissue that has been regurgitated into the abdominal cavity during menstruation. We have previously shown that menstrual effluent induces epithelial to…

BACKGROUND: Not all women with patent tubes develop clinically manifest endometriosis. Quality and quantity of endometrium in retrograde menstruation may be the determining factor in the development of the disease. We hypothesize that retro…

The chick embryo chorioallantoic membrane (CAM) bioassay was used to investigate the early pathogenesis of endometriosis. Endometrial fragments were explanted onto the CAM. The grafts including the surrounding CAM were excised at 24, 48 or …

Previous in-vitro studies have shown that the endometrium preferentially adheres to the extracellular matrix (ECM) of the amnion and peritoneum. This interaction probably involves adhesion molecules, e.g. integrins. We evaluated the express…

In a previous study on the pathogenesis of endometriosis, we observed that constituents of menstrual effluent induce morphological alterations in human mesothelial cells. In this study, we investigated whether these alterations were associa…

One of the first steps in the pathogenesis of endometriosis is the attachment of the endometrium to the peritoneal lining. Since the peritoneum is extremely fragile and hard to obtain, amnion has been used as an in-vitro model to study adhe…
